EECIV and F3 evaluate tune on chip

Anything about Ford EEC tuning. TwEECer and Moates questions dominate, but there's some SCT and OBD-II knowledge too.

EECIV and F3 evaluate tune on chip

Post by Cruisin428 » Thu May 31, 2018 11:29 pm

Overview of my situation:
I inherited this SB Ford with the A9P and Moates F3 chip. It pops and sputters when under power - It seems to run better at WOT (It just hit me at WOT it goes open loop so this points to the tune being bad??) Although I can only manage WOT for a second or two.
My problem is I drove the car and it ran OK, then was parked for 4 months, then delivered to me, I don't know what EEC it had? Maybe the same or a different one? When I received it, it ran bad from coming off the truck, so I am starting from scratch with no baseline of it ran fine but now I am trying for more power or I'm changing something so need to change the tune.
Also I found the EEC had the three bad caps in it. All three had legs that were "open". I changed the caps and checked the traces (all good) and tried running the car, but it has the same popping and sputtering, although it feels different. Still does not run well enough to try to drive it!

What I am trying to figure out:
I pulled the bin off the F3 - and now I am trying to evaluate the tune and
1 Find out how far off the original tune is
2 get a tune for the engine that will get it to a baseline so it will run
3 after checking the tune, make sure all components are working correctly. (MAF, MSD, O2, fuel)

Things I have done up to this point:
Checked timing
checked compression - All within 5 psi of 145
changed plugs
checked and set TPS - Setting the TPS at 1.11 (about as far it would go) or higher seemed to make it run better
Tried to check the MAF (with DVOM) - 90mm ford lightning
checked fuel pressure - about 45 PSI
checked the O2 sensors (with AVOM) - I think they are bad (slow to respond or stuck on one voltage) they are on the list to replace after I check the tune - although it does not run any better when in open loop when it is cold

Hardware on the car:
347 I assume
AFR 205 race heads
cam is ???
90mm Ford MAF
Siemens Deca 60 # injectors
MSD 6AL and pro billet distributor
Vortech V3 blower - currently with drive belt removed.
Stick Shift
No smog, EGR, or other junk

Question:
If anyone would look over the bin and point out any problems or any thing that is right for that matter I would greatly appreciate it.
I really don't want to use this engine as a tuning learning tool and burn it up!!!!
one thing I notice the bin has 331 CI listed!

If I feel confident that this setup will work I am going to order a QH to data log it (I got the BURN2 to pull the bin). If not, the only other option I know of is to get a MS and start from square one with it!
Thanks to all of you for looking!!

If all you do is Fords, I'd recommend a Jaybird and a QH. Hell, maybe even upgrade to the F3v2
1990 Ford Ranger FLH2 conversion. Ford forged/dished pistons, Total Seal file-fit rings, Clevite rod and main bearings, Clevite cam bearings, IHI turbo, Siemens Deka 60lb/hr injectors, Ford slot MAF in custom 3" housing. Moates Quarterhorse with Binary Editor, using the PAAD6 database.

Since you already have a Burn 2 and adapter to read the F3, there is nothing to gain getting a jaybird. Get the QH so you can start logging.
Did the bin you pulled match a A9P strategy?
85GT, 302 w/Dart Windsor Jr heads, Crane 2030 equiv. Performer 5.0, 75mm TB, 88mm slot MAF, 34lbs injectors, BBK shorties, 5spd converted to 4R70W with Baumann controller, 9" rear w/3.25s

It looks like the bin is a FTOL GUFB A9L tune. There were too many errors using the GUF1 A9P strategy but none with the GUFB. I here you can do this with a Quarterhorse but no idea with the chip. There does however seem to be a lot of undefined differences and I suspect the tune was built using TunerPro and an A9L2 base bin.

Here is a list of the defined differences as compared to a stock A9L read

asterisks in the functions and tables indicate no change.

Just to rule out incompatibility, I would load an A9P bin with the basic changes to see if it behaves any better.
1987 Turbocoupe.
A3M1/A9L, BE/EA, Tweecer RT.
306,Single Turbo, Ported E7's, Ported Stock Intake, 42lb Matched Green Tops, PMAS 3" Blow-Thru Protube (42# supercharger calibrated),T5z, 3.73 gears
..... Nothin Fancy.......Just something to keep me from the honey-do list.........

First, I can not thank everyone enough for the reply's. Working on cars is fairly simple and working on computers is fairly simple. But so far, my ability to work on car computers (tune) is very lacking.

Here is the stock A9P bin off the EEC. I did not think it would be helpful, so I did not add it the first time.

Skunk,

Thanks for the evaluation, I need to read up on the different strategies, and I was thinking using the A9P bin, adjusting for the major changes on the motor might be a starting point.

I have not received my QH yet, so not able to data log.
